l o 1N fur/mmy it may concern:

im it known. that 1, ROBERT D. BAssnrr, a citizen or' the United States, residing at Kinzua, in the county ot' lVarren and State of Pennsylvania, have invented a new'and useful Process of Recovering and Grading Gasolene, of which the following is a specificatiorn This invention has reference tc improvements in the process of recovering and grading gasolene, whereby gasolene ot' any desired degree of specific gravity may be produced 'without the necessity of resorting to the wasteful methods now employed, especially where it is desired to produce a gasolene of' lower degree from high degree gasolene or treni the gas from which the latter may be produced.

In accordance with the present invention a gasolene of the desired degree of specific gravity is produced by mixing light highgrade gasolene, that is, gasolcne of high degree Baume, and gas from which such gasolene is takenA but which is still rich in gasolenc` or the rich gas before the high-degree gasolene is taken therefrom, with a relatively heavy or low-degree hydrocarbon, usually in the forni of a gasolene of lowgrade Baume, the proportions employed being such as to produce a blend of the desired degrin from the high and low degree gasolenes.

The result ot the process of the presentv invention is that there is obtained a greater output of gasolene. from the rich gas than has heretofore been the raso, While the blend ,(f y:rasolenes constituting the gasolene of rnediuin grade or degree is reliably stable.

The great inflainniability of high degree gasolcne because it is so highly volatile, and the consequent danger to life and property in handling such gasolene has caused the railroads and `other cornmdn carriers to adopt. regulations with respect'to the degree oit specific graiity of the gasolenc which will be accepted for transportation. Many cornnion carriers refuse to transport gasolene which is higher than seventy-eight or eighty degrees, wherefore the shipper must reduce his high degree gasolenc, say of ninety-one degrees, to seventy-eight or eighty degrees,-

and this has generally been done by permitting a portion ofthe gasolene to evaporate,

t 1companying drawings mdicating an apparatus by which the process may be practised, but it will be understood that the process is not necessarily limited to the use ot' the apparatus disclosed, nor to the exact procedure described, wherefore it will be further understood thaty the invention is susceptible of various changes and modifications so long as such changes and modifications do not mark a material departure from the salient features of the invention.

In the drawings :"-Figure 1 is a diagram with some parts in elevation indicating an apparatus whereby the process may be carried out. Fig. 2 is a cross section of one of the mixing and condensing devices.

In the drawings there is shown a reservoir 1 which may be assumed to be of suitable capacity, and which is to be taken as indicative of any suitable source, such as a well or tank, of gas productive of high degree gasolene. ln the subsequent treatment the gas, and the high degreel gasolene when present, are undey considerable pressure, say about one hundred and'forty pounds per square inch, and this is typified in the drawings by a pump 2 connected to the reservoir or tank 1, and from the pump the compressedl gas passes b v a pipe 3 into a cooling device 4. when it is desired' to first condense high degree gasolene 'from the Gas. rl`he cooling device may consist of a simple casing inclosing a coil 5 connected at one end to the pipe 3 and at the other end to another pipe (i, ay cooling fluid, such as water, entering the casing 4 through a pipe 7 and escaping through a pipe S, all the parts being more or less typical of any suitable apparatus forthe purpose. After passing through the cooler et when included in the system, the high degree gasolene with the accompanying gass conveyed throughsy casing 9 provided with a bottom extension 10 terminating in a reducing coupling 11 to whiclrisconneclted a valve 1Q, so that any water or the like which may reach the cas ing 9 will find its way into the extension 10 andfrom time to time may be` drawn 01T.

soA

through the valve 12. lLeading out -from the casing 9 is a pipe 18 ultimately terminating at a T coupling 14. There'is also indicated a reservoir or tank 15which may.

be taken as typical of anysuitable supply* of low degree gasolene or high degree kerosene, either of which may be considered las a relatively heavy low-'grade hydrocarbon liquid, and while reference will hereinafter be made particularly to low degree gaso- `lene, it will be understood Without further explanation that under some circumstances high degree' kerosene may be employed in place of the low degree gasolenc. Thev reservoir 15 is connected by a pipe 16 through a valve 17 to a pump 18, and the latter i3 connected by a pipe 19 through a valve 20 Ilatter serving to wholly cut-ofi' the supply l may be generally alike.

.screwed at the ends into hollow heads'23, 24,

respectively, Land the. casing 22 isv screwed between the pump 18 and the T 14. when desired. There are also provided two elongated casings 21 and 22,.respectively, which The casing 21 is .at the ends intoy other hollow heads 25, 26,

respectively, `fthe l.several heads being substentially alikc,-and each is provided with an intermediate diaphragm or division wall 27, while the end oit each head remote rom that* into which the respective casing. 21 or 22 is screwed is fdrmed with a circumferential flange 28 designed to receive a cap plate 29 held in place by blolts '30.

\n Win be unda-awaited, tout in the" parts already ,described and in the parts to be described, suitable proision is made b packing 'or otherwise for preventing leak age, it being deemed unnecessary to either show or describe any means 'for such pur- Jose.

l Each. diaphragm or ldivision wall 27,'is traversed by a. suitable number of passages through which extend corresponding ends of pipes 31, these pipes being held in-place by nuts 32,vand each pipe opens into a chamber formed between the respective'diphragin 27 and cap 29. There is no coin'- munication between the interior of the casing 21 or 22 and the terminal chambers in the heads at the ends of the casings formed between the diaphragnis 27 and the caps 29, but the chamber at one end of each casing 21 or 22 is in constant communication with the. like chamber at the other end thereof through the pipesV 31, the latter being grouped in spaced relation one to the other vand to the walls of the respective casing through which they pass..

The T' 14 is connected ,with

A' 22 about the pipes 31 ltherein.

e from ythe head 26 at that end communicatt-he interior" ramasse- '.v

of' the lternzii'nalv chamber within the. head 23. by a` -pipe 33..' 'The terminal chamber within'the head'24 ris connected to the like terminal chamber within the head 25'by a pipe and leading rom 'thc .terminal chamberwithinth'e head 26 is -a 'pipe 35 entering oneend of a separator 36 designed to separate liquid gasolene from the gas accompanying-it, and sin-.cc vthis separator is -of known lconstruction,it is neither showrrv nor described in detail. The liquid gasolcne leaves .the separator 3G byl a pipe 37, while, the .lean gas leaves the .separatorby' a pipe 3 8,'which in turnis connected with the 'head 23, on the `side of 'the diaphragm 27 therein. remot'efrom' the cap 29, so that the gas .willxow .through'-the casing 21' about the pipes 3l to thehead 24, whence the gaspasses out of. the casing by way ot a pipe39 leading to a'coil 40 .within a casing 41si'1'n'ilar 'to the coil 5 within the casing 4. 1 1The ycasing'41'may receive a heating meldium through a pipe 42, and such heating medium'after performing its oiii'ce may escape fromthe casing 41.by way of a pipe 4 8. The gas becomes chilled by expansion and, Atherefore,.the heating coil 40 is employed to prevent freezing of vcertain valves through which the gas is subsequently con* ducted.A 'That end of the -coil 40 remote from the pipe 39 is ,connected toa pipe 44 including e' valve iti-,and the pipe'44ftermi- -nates at a T46 from one side of which there is branched ia pipe 47 including a valve 48,

. and fromv Athe othe-rsiderof which there is branched a. -pipe` 49' including a ,valve 50. The pipev 49 is connected with the interior ofthe head 251ontlie sideof the diaphragm 27 remote from the cap l29, sothatfgas enteringthe head 25 by way of the pipe 49 has free access.v to the interior of the casing lLeading ing with the casing 22 is a pipe 51.
